Intravenous Pyelogram: X-ray of the kidneys

An intravenous pyelogram (IVP) is a type of X-ray that allows visualization of the kidneys and ureters after the injection of a contrast dye. The dye helps enhance the image on an X-ray film. As the contrast dye moves into and through the kidneys, ureters, and bladder, X-rays taken at short intervals can capture its movement. A delay in the contrast dye moving through the urinary system may indicate an obstruction in the kidney's blood flow or poor kidney function. This test is usually ordered as one of the first tests in cases of suspected kidney disease or urinary tract disorders.

Reasons for the procedureThis test is recommended for the renal stones and obstruction. An IVP can demonstrate the size, shape, and structure of the kidneys, ureters, and bladder. It can also be used to evaluate kidney function, the presence of kidney disease, ureteral or bladder stones, trauma or injury, and tumors.

A CT scan of the kidneys can also perform instead of IVP which aids in more accurately diagnosing. There may be other reasons for your physician to recommend an IVP.

Risks of the procedureIf contrast dye is used, there is a risk for allergic reaction to the dye. Patients who are allergic to or sensitive to medications, contrast dye, or iodine should notify their doctor. An allergy to shellfish, while previously thought to be related to a contrast allergy, is no longer relevant.

Preparation

At 10:00pm take four (4) Dulcolax tablets with at least one full glass of water. Do not crush or chew the tablets; swallow them whole.

Do not eat or drink anything after midnight or atleast 06 hrs before the examination.

Before the procedure

You will be asked to sign a consent form that gives your permission to do the procedure.

Contrast dye will be injected into the IV. You may feel some effects when the dye is injected into the IV line. These effects may include a flushing sensation, a salty or metallic taste in the mouth, itching, or nausea and/or vomiting. These effects usually last for a few moments.

A series of X-rays will be taken at timed intervals, generally over a 30-minute period, as the dye travels through the kidneys and urinary tract. You may be asked to assume various positions while the X-rays are being taken.

You will be asked to empty your bladder. You may be given a bedpan or urinal, or you may be allowed to go to the restroom.

After you have emptied your bladder, a final X-ray will be taken to examine the amount of contrast dye remaining in the bladder.

After the procedureYou may resume your usual diet and activities, unless your doctor advises you differently.

You should have fluid intake and amount of urine voided over the next 24 hours. You may be instructed to increase your fluid intake in order to help flush the contrast dye from your body.
